Application filed August 18, 192%. Serial No. 732,844.

The objects of the invention are to provide automatically acting means for supply, ing the explosive .mixture of an explosionengine with an added charge of moist air,

passage for hot moist air leading preferably from the radiator of the car thereto, and a passage for dry air, both passages communi- '2 eating with the intake passage of the engine. The invention is illustrated in the accompanying drawings, hereinafter described and specifically pointed out in the claims.

The device is possessed of many advantages, among which may be enumerated an increased amountofpower produced by the action of the moisture which tends to lubricate the engine parts and to prevent the deposit of carbon thereon, It also tends to make the action of theengine smooth and quiet. Also since the excess of fuel oil is deflected orwithdrawn from the charge, a

more perfect mixture and more perfect coinbustion is produced. Also since the excess of fuel oil is drained away from the charge and is afterwards reintroduced therein, the device-will avail to utilize all the fuel and eliminate waste.

It indludes a chamber for the deposit of 49 fuel oil and a passage through which an ex cess of fuel oil leads to said chamber, and

from which it may be drawn, commingled with a supplyof hot moist air and of dry air, thus enriching the charge as well as sup 4 plying moisture to the same.

In the drawings, Fig. 1 is aside elevation of the engine of a motor car, showing the location of the device, and its connection with the carburetor and intake pipe or manithe radiator; Fig. 2 is a verticaltrai'isverse section thereof online 1-1 Fig. 3; Fig. 3 is an edge elevation thereof.

In these drawings, A represents the' car buretor, B represents the manifold, (3 rep resents the combined moisture and dry fold of the car, and also'its connection with supplying the fuel oil salvaging device. D

represents the source, such as the.- radiator,

from which hot, moist air maybe supplied to the device, E represents a tube for supplyingmoist air to a chan'iber F in the body of the device, through the orifice Hgis a second chamberin this body into which dry air enters through the orifice h and separated from the chamber F by a partition F and J is a bent tube, the extremities K, K of which enter these chambers and through the upper openings L, L in which moist and dry air are thrown by engine suction into the manifold,

On the bottom of the passage 5 passage C, abafiie N is elevated to extend 1nto the passage C, and check the passage 'of any waste fuel oil or excessive amount thereof in the charge, which is then drawn through the opening 0 adjacent to the bottom of the passage and preferably intothe dry air passage in the tube K, and is commingled with the additional'supp'ly of hot,

moist and dry air drawn through the sides K, K of the tube F,1into the intake pipe through the opening P in the partition separating the chambers F and H, thus utilizing and consuming all the fuel oil with out waste, and preventing the production of an over-rich mixture.

A closure .Q in

, p in this dev ce, which is a continuation of the intake the air admission tube above the opening O prevents suction from drawing the air and waste fuel oil directly into the. intake passage, but requires it to be n'iixed with hot moist air and with an additional supply of 7 dry air, thus making a more perfect mixture before entering this, passage.

By the use of this device the tendency car drivers to speed up and use too rich a mixture is corrected.

Having described the invention, what I claimas new and desire to secure by Letters Patentis: I

1. In a device of the character described,

a sectionor member inserted in the intake passage of an explosion engine, said member containing a continuation of said passage, chambers therein communicating with said intake passage, a pipe leading to one of said chambers'from a source of hot moist air, the OthGlf'ChfllllbBl being provided with an air inletopening, said interposed member extending upward partially across said intake passage, and a discharge opening-for waste fuel oil in said passage leading from one 'side of said interposed member to one of said chambers therein.

2. In a device of the character described, a section or member inserted in the intake passage of an explosion engine, said member containing a continuation of said passage, chambers therein communicating with said intake passage, a pipe leading to one of said chambers from a. source of hot moist air, the other chamber being provided with an air inlet opening, said interposed member extending upward partially across said intake passage, and a discharge opening for Waste fuel oil in said passage leading from one side of said interposed member to one of said chambers therein, and a V-shaped pipe having its extremities inserted in said chambers and projecting into said intake passage, said projecting portion being provided with a suction opening.

In testimony whereof, I hereunto set my hand this 16th day of August, 1924;.
